Two-body $J^{\pi}= 0^+$, $1^+$ and $2^+$ resonances of the $Y_c$ ($=\Lambda_c$, $\Sigma_c$, or $\Sigma_c^*$) and N systems are analyzed by the use of the complex scaling method. We employ the $Y_c N$ phenomenological potentials, which are composed of the long-range meson-exchange force and the short-range quark exchange force. We find four Feshbach-type resonance states slightly below the...
It is shown that the existence and the creation of a monopole in Non Abelian Gauge Theories are gauge invariant and Abelian Projection independent concepts.
This puts on a firmer basis the construction of an order parameter for confinement.It also suggests a reinterpretation of old lattice data on monopoles.
We investigate kaon-nucleon interactions in the Skyrme model with the new quantization method. It is based on the bound state approach but is more suited to the weakly bound system. The spatially extended structure of the nucleon as a soliton enables to express the interaction as an $r$-dependent potential. We find that for the isospin 0 antikaon-nucleon system the potential consists of an...
